200LX

Here's LXPGP(click to download) LXPGP Version 1.0 a Front-End to PGP 2.6.x written in LXBatch for the HP 100/200LX. It is executed like a normal LXB script, but a compiled version is also included for those without LXBatch. Take a look at my LXPGP screen captures page to see what it looks like.

Here is how to install and setup LXPGP:

I use Software Carousel to give LXPGP the maximum amount of memory and it also allows me to have LXPGP always running but also be able to open other shells, and to have a clear System Manager to work with. DOSShell works great too, and I have an installation guide detailing how to install and use DOSShell. Also, you can use SMMX which can be downloaded from the Thaddeus Webpage (it is listed as being Japanese software, works great for me. I use it in place of the normal More... GUI, definately check it out if you haven't) or HDM which is a DOS menu program similar to the System Manager GUI combined with MAXDos which both can be gotten from the Super Page page, and while it gives you a DOS Shell with lots of free memory available for PGP it doesn't do task switching or such, so it can only be used one at a time.

I normally use HDM to launch LXPGP in a Software Carousel session, setting the path/filename to simply LXPGP.BAT and setting an icon. LXPGP can be launched from within EMail programs, directly from PalEdit, etc.., as it is quite flexible. More information on that is included in the documentation.

For use in DOSShell, I created a 'New File' under the Program Manager in DOSShell with a title of LXPGP, the command as LXPGP.BAT, my application shortcut is SHIFT+CTRL+HPCALC. I left the mode (under the Advanced section) as Text because DOSShell jumbles the graphics when returning to a graphics screen. I have to get into a text mode (such as using PGP) in order to task switch, which is kind of annoying but it's very usable. However, if you set the mode to Graphics in DOSShell under the Advanced section in Properties and then task switch, it does indeed make the screen look funny, but if you reset the screen by Other Run editor for instance, it will clear up the screen so exiting LXPGP isn't necessary, and that's what I now do. For use under System Manager, here is an icon to use with SMMX and in the Application Edit screen I put &LXPGP; for the name, MaxDOS LXPGP.BAT in the Path, and set the Icon.

Software Carousel/DOSShell and MaxDOS aren't required to run LXPGP, but are required to run PGP. It require at least 340k free in a DOS shell to run LXPGP and to encrypt a text file.

Did you utter configuration? Well, yes, I suppose configuration is required. But, LXPGP does it for you, so to speak. When you first execute the program it will introduce itself and then go into a configuration dialog. Simple stuff, first you are asked for the path to your favorite editor (any DOS editor will do, RED, PalEdit, MicroEmacs, etc.. Most likely the tricks to use Memo won't work though.), I put C:\PE\PE. For some odd reason, if you're calling a *.BAT file it doesn't work, and returns Bad Command on the shell then returns to LXPGP. If this happens and your batch file is in the path, try just putting the name of the batch file, such as PE rather than PE.BAT. I've tried and tried to figure out the problem, hopefully will fix it someday. :) Next, you're requested for the path to the PGP keyfiles, for me it's C:\UTILS\PGP\. It writes the configuration to C:\_DAT\LXPGP.CFG and it's ready to go! If you ever desire to change your configuration, you can do it through LXPGP in the Other menu or you can edit it with your text editor, it's nothing fancy. There are other options that are explained in the LXPGP documention, both the 'online' help and the DOC file.

A small help system is built into the program, it simply helps explain what the different menu choices do. If you don't currently use PGP I suggest first off going into the Keys menu and selecting Generate Key. I use a 768 bit key, you may desire a larger one. You can either type the size (up to 2048 bits) or choose one of the sizes given to you (pick 3 :). It takes a while to generate, so be patient. And yes, it does require all that typing to generate a key for you, it's using your keystrokes to create a 'random' bits to go from, like it says. And when it comes time to choose a secret passphrase, pick a good long one! And I suggest you don't put it in the Notebook so you don't forget, at least not directly (maybe mix up pieces here and there if you need to).

If you already have a public and secret keyring, you can do what I did, simply download them to the palmtop! Assuming you're using PGP 2.6.x on your home computer. If it doesn't work, then you can always generate a separate key for the LX, it deserves it. :)

Speaking of which, here is my public key which you're invited to add to your public keyring after you have your own key created. Also, don't forget to look for your friends and software authors who have surely put their public key on the public key server. Be sure to add your key after creating it too.

I've also created a small screen captures page. Check it out if you're curious just what LXPGP looks like!

Have fun, and let me know if you have any comments or questions. Releases will be posted here as I update/correct so check back.



Thanks for your interest in LXPGP!
